Half of the SMTP relays on the Internet are EXIM. A huge number of Service Providers use EXIM, and it's popular with blackbox appliances used for filtering and security too.
As much as I'm considered a 'red Fedora,' Debian w/EXIM out-of-the-box is something I consider a 'best practice.' The lack of having to pipe things, like in Postfix (let alone Sendmail), is why I prefer EXIM, and Debian does an excellent job with it out-of-the-box. And most Service Providers use a 18-36 month refresh, so Debian itself is very popular too. And being IT-centirc, they have enough staff in-house to make it very viable. In fact, Debian is very well built by these organizations. So they traditionally don't run more 'Enterprise' labeled distributions with SLAs. Although it is my hope that now that RHEL Stream has become public CentOS Stream as of 2019, it will increasingly become popular for such things too. I hated not working at a major account, and not having access to Stream prior to 2019. Beyond Wall Street and Hollywood, the bigs [among providers] (Facebook, Twitter) have long run Stream, and now that it's public, they have have public SIGs and development in the open, like their HyperScale modifications that will never be a part of RHEL, but may be in the next RHEL. -- Sent from my phone, apologies for any brevity as well as autocorrect Bryan J Smith - http://linkedin.com/in/bjsmith On Wed, Oct 25, 2023, 07:49 Simone Piccardi via lpi-examdev < [email protected]> wrote: > On 25/10/23 00:33, Anselm Lingnau via lpi-examdev wrote: > >> Could it be that Exim is embedded in some popular product that makes > >> them come out on top? > > > > Exim remains the default MTA on Debian GNU/Linux, which is a reasonably > > popular Linux distribution. > > > > That probably explain the number on the report, but how many of these > Debian server are MX server? > > That statistic would be far more meaningful if restricted to servers > corresponding to an MX record. > > Simone > -- > Simone Piccardi Truelite Srl > [email protected] (email/jabber) Via Monferrato, 6 > Tel. +39-347-1032433 50142 Firenze > http://www.truelite.it Tel. +39-055-7879597 > > _______________________________________________ > lpi-examdev mailing list > [email protected] > https://list.lpi.org/mailman/listinfo/lpi-examdev
